I’ve been re-reading (after a long time) David Landes’ The Unbound Prometheus, having found a 2nd hand copy in a Sedbergh bookshop, Westwood Books, earlier this year. It’s an interesting read, albeit showing its age (I found a 1993 edition, but the first was 1969). I’d forgotten that he looked at post-2nd world war growth in the final chapter, which also concludes with some reflections about the links between technological innovation and economic growth.

“The effective utilization of scientific and technical knowledge requires a whole sequence of decisions and action in the world of production and distribution. Pioneering entrepreneurs and managers must be prepared to risk money on the translation of ideas into commercially feasible techniques; while others must be incited by the prosepct of gain, or the fear of loss, to follow suit.” He goes on to say that the quality of management, the skills of the workforce, consumer tastes must also fall into place. “Scientific creativity is by no means an assurance of growth.” Interesting to see Paul David’s argument in The Dynamo and the Computer prefigured here. Growth is “a marriage of knowledge and action”, not the outcome of the impersonal forces of supply and demand.

Above all, growth will vary according to the particular needs, opportunities and history of different economies. Even the role of government varies greatly, Landes argues. The common factor in the postwar period, however, was, “A revolution of expectations and values. The expectations were not new; they were a return to the high hopes of the dawn of industrialization, to the buoyant optimism of those first generations of English innovators. Yet never before had they been so widespread; and never before had they been so strikingly confirmed by the facts.”

The trentes glorieuses seem like prehistory in today’s unsettled world. I’m not a techno-pessimist, and disagree with Robert Gordon’s thesis. But vision (expectations, we might say in economese) is a constant that really matters. I’ve always liked Paul Krugman’s 1991 QJE paper, History versus Expectations, on the importance of people weighting the future as more important than the past, if an economy is to grow. No high hopes, no growth.
